[Bug fortran/44036] I can't declare an external function in an OMP shared statement.

I'm not convinced that external (without pointer attribute) objects are allowed
in the shared etc. clause lists.  The OpenMP 3.0 standard says that a list item
is a variable name or common block name.  And the definition of variable is:
"A named data storage block, whose value can be defined and redefined during
the execution of a program."

Does integer, external :: f satisfy this?

What would it mean whether f is shared, private etc.?  All you can do with
that is call it.

On the other side,
integer, pointer, external :: fp
I'd say is a variable, but internally in gfortran is FL_PROCEDURE too.  The
pointer can be changed to point to some other procedure, has associated
storage, etc.  So I guess a patch like #c1 that allows attr.external
attr.pointer FL_PROCEDUREs.

is something we want to do.  Bu
